v0.7.1 — fix silent osascript wake keystroke race
Patch release.
Bug: claudemb-wake.sh used tell application "System Events" to keystroke which routes to whichever process is frontmost at execution time. If Claude.app didn't fully take focus during the 0.3s activation delay (multi-window, focus contention), keystrokes landed in the user's actual foreground app with NO error logged. @claudemm observed ~10 lost wakes in a 16-min window on the mini.
Fix: bind the keystroke target to the process explicitly via tell process "$APP_NAME" / set frontmost to true / keystroke. Plus a post-keystroke verify check that logs WARN when finalFront != target for any remaining edge cases.
Affected: anyone using the AppleScript wake path (claudemb-wake.sh in the IAK poller). The Stop hook path (claudecode-stop-resume.sh) was unaffected — it uses exit code 2 + stderr, no keystroke.
